Isamu Akasaki and Hiroshi Amano of Nagoya University, Japan and Shuji
Nakamura of University of California at Santa Barbara, have been awarded the
2014 Nobel Prize in physics for the invention of the blue LED.
Though blue LEDs are quite often seen these days on architectural
structures, the ability to create blue light with LEDs had eluded scientists
for years - without blue light, one cannot create white light. Blue is one of
the primary colours required to create white light.
Over the past few years, white LEDs have advanced tremendously in design
giving greater light outputs with vast improvements in energy efficiency. In
addition to a significant reduction in energy consumption, white LED lighting
also reduces the strain on landfill by eliminating the need to constantly
replace light globes and fluorescent tubes.
There is no doubt, LEDs are highly energy efficient; however, one must
ensure a good quality LED power supply, also known as the LED driver. A poorly
designed driver can counteract the efficiency gains associated with LED
lighting.
MeanWell is a world leader in designing and manufacturing highly
efficient, reliable LED drivers. MeanWell’s HLG series is a favourite amongst
OEMs and installers due to its high efficiency rating of up to 96% and high
reliability, which is backed by a 5-year warranty.
MeanWell LED drivers are available in Australia from ADM Instrument Engineering .
